本研究針對衛星的天線展開機構，進行系統化的分析和設計，首先說明衛星天線展開機構之基本概念，定義何謂衛星天線展開機構，並針對現有展開機構進行系統化的分析，歸納其機構拓樸構造，依照展開機構構造上的特性，將展開機構分成線性展開機構、面展開機構、以及體展開機構三類；同時依照展開機構的功能，將其進一步分解為啟動裝置、展開裝置、以及固定裝置等三個主要子系統。接著本研究以顏式創意性機構設計方法為基礎，提出一套系統化之衛星天線展開機構設計方法，並針對太空環境和衛星操作條件，利用品質機能展開法（QFD）進行一般性的工程規格訂定，將定性的設計需求轉換為定量的工程規格。此外，本研究以二種具備不同天線展開機構需求之衛星為例，進行實際的設計和分析；設計實例一為線性展開機構，設計實例二為面展開機構，針對此二種衛星天線展開機構訂定工程規格，進行機構概念設計和細部設計，接著分析其運動、動力、以及動態特性，並以CAD軟體建立實體模型與模擬，驗證出設計結果之可行性。本研究將其中一衛星天線展開機構原型機實做出進行測試，完成我國太空計畫室籌備處立方體衛星計畫蕃薯號衛星（YamSat）之天線展開機構。本研究之成果，可做為日後系統化設計衛星天線展開機構的參考依據。

The aim of this work is to conduct systematic analyses and designs on the antenna deployment mechanisms of satellites. First of all, the basic concepts and definitions of satellite antenna deployments are introduced. By analyzing existing designs systematically, the topological structures of deployment mechanisms are concluded. According to structural characteristics, deployments can be classified into three different types: linear deployments, surface deployments, and volume deployments. And, deployments can be further divided into three subsystems including starting devices, deployment devices, and fixing devices in terms of the function of their components. Based on Yan’s Creative Mechanism Design Methodology, this work provides a systematic design approach for satellite antenna deployments. Considering the space environment and satellite operation conditions, Quality Function Deployment technique is then applied to convert qualitative design requirements into quantitative engineering specifications. Furthermore, this work selects two satellite antenna deployments that have different design requirements as design and analysis examples. The first example belongs to linear deployment, and the second belongs to surface deployment. Then, the engineering specifications and the conceptual and detail designs of mechanisms of the two examples are determined. After that, the kinematic and dynamic analyses are put into practice, and the computer modeling and simulation are applied with CAD software. The results verify the feasibility of the design. This work builds the prototype of the first example, which is the antenna deployment of the YamSat, the cubesat project of NSPO, and tests its performance. The output of this work can be used as a reference for the systematic design of satellite antenna deployments in the future.
